Theo
A scalable design system for an AI-powered real estate platform

Theo builds an AI operating system for real estate ownership, replacing the fragmented, pen-and-paper workflows landlords have relied on for decades with one connected interface. Three years ago, as hallo theo, the Berlin startup set out to fix this notoriously analog industry — and has since scaled to 20,000 homes across five cities in Germany.
A Color Bright redesigned the brand from the ground up to match that momentum: a new logo, a new visual language, and a new marketing website, designed and built alongside it. hallo theo became Theo — shorter, more confident, and built for the scale ahead.
My main focus was building a scalable design system based on the brand's updated visual identity, giving the new product a consistent foundation to grow on.
Project Goals
- Modernize the application by reworking the navigation and app chrome while defining layout guidelines1
- Envision future product features to make sure the design system covers enough ground2
- Build the design system in a agent friendly way to speed up implementation time3
